Definitions

  • This disclosure relates generally to fluid flow regulators and, more particularly, to apparatus to regulate high pressure fluid flow which includes a valve member deformable to distribute forces to a valve seat.
  • regulator valves in a wide variety of applications such as, for example, controlling the flow of a gas or fluid in a processing operation.
  • the regulation of the flow of gas requires that a regulator valve accommodate a high flow rate of gas at high pressures and maintain the purity of the gas.
  • a manufacturer of such regulator valves may certify that the valves are free from contamination by particles created or left behind during the manufacture of the valves.
  • regulator valves may experience contamination in the form of particles introduced into the regulator valve during or after manufacture. The presence of contaminants may result in damage to parts of a main orifice (e.g., a seat) of the regulator valve and cause a significant leak to occur.
  • An apparatus to regulate fluid flow comprises a housing having an inlet and an outlet, a valve seat at a valve passage wherein the valve seat defines a first diameter surface extending to a larger diameter second surface, and a valve member is movable to engage the valve seat.
  • the valve member has a deformable member to engage the first diameter surface of the valve seat and deformable to engage the second surface.
  • FIG. 1 is a cut-away illustration of an example fluid flow regulator valve.
  • FIG. 2 is an enlarged view of the circled portion of FIG. 1 .
  • example apparatus described herein may be utilized for regulating fluid flow in various types of fluid flow processes. Additionally, while the examples described herein are described in connection with the control of product flow for the industrial processing industry, the examples described herein may be more generally applicable to a variety of process control operations for different purposes.
  • FIG. 1 is a cut-away illustration of an example fluid flow regulator valve 100 .
  • the example fluid flow regulator valve 100 includes a body or housing 110 having an upper housing 112 defining a chamber 113 , a lower housing 114 defining an inlet chamber 132 , and an adjustment housing 116 received by the upper housing 112 at threaded connection 118 .
  • An adjustment screw 120 has a threaded end 122 received at threads 124 of the adjustment housing 116 .
  • the adjustment screw 120 engages an end member 126 which abuts a resilient member or load spring 128 located within the adjustment housing 116 and the upper housing 112 .
  • the lower housing 114 includes an inlet 130 and an outlet 140 .
  • the inlet 130 communicates with the inlet chamber 132 in which is located a valve spring 155 .
  • a main valve is designated generally by reference numeral 160 .
  • the valve spring 155 engages a lower end 161 of a valve stem 162 to urge the valve stem 162 toward the upper housing 112 .
  • the valve stem 160 has a deformable valve member 164 .
  • the deformable valve member 164 has a generally flat angled surface 164 B that engages a valve seat 166 of an orifice or passage 167 disposed at a stem cap 168 .
  • the stem cap 168 includes lateral openings 169 to permit fluid flow to a passage 142 communicating with the outlet 140 .
  • a valve guide 180 is located between the upper housing 112 and the lower housing 114 .
  • the valve guide 180 has a central opening 182 receiving the valve stem 162 , and radially outer through openings 184 for fluid flow therethrough.
  • the valve stem 162 extends upwardly to engage threadingly, at threads 186 , a movable sensor 190 .
  • the movable sensor 190 is located within the chamber 113 of the upper housing 112 .
  • a diaphragm 200 extends between a sensor flange 192 and the valve guide 180 .
  • the load spring 128 is received within the sensor 190 to urge the sensor 190 and the valve stem 162 downwardly toward the lower housing 114 .
  • the adjustment screw 120 may be rotated to adjust the force of the load spring 128 upon the sensor 190 and the valve stem 162 .
  • FIG. 2 is an enlarged view of a portion of the main valve 160 circled in FIG. 1 .
  • the deformable valve member 164 is a unitary member mounted upon the valve stem 162 .
  • the deformable valve member 164 may be made of numerous nonmetal materials such as, for example, polychlorotrifluoroethylene or PCTFE (NeoflonTM) or polytetrafluoroethylene (Teflon®), which may deform substantially when engaging the valve seat 166 .
  • the deformable valve member 164 engages the valve seat 166 to close the passage 167 and prevent fluid flow therethrough.
  • the valve seat 166 includes a first diameter surface 166 A that has a corner 170 and extends radially outwardly to a larger diameter second surface 166 B.
  • the larger diameter second surface 166 B is a flat angled surface offset from the first diameter surface 166 A and disposed parallel to the flat angled surface 164 B of the deformable valve member 164 .
  • the larger diameter second surface 166 B can be configured in other shapes such as, for example, one or more surfaces or corners similar to the first diameter surface 166 A but offset from the first diameter surface 166 A, one or more undulations offset from the first diameter surface 166 A, or other shapes which are offset from the first diameter surface 166 A.
  • the example fluid flow regulator valve 100 receives high pressure fluid or gas such as, for example, hydrogen chloride, at the inlet 130 .
  • the fluid flow regulator valve 100 is closed because the adjuster screw 120 is retracted upwardly such that the load spring 128 permits the valve spring 155 to displace the valve stem 162 upwardly.
  • the deformable valve member 164 engages the valve seat 166 (see FIG. 2 ) to close the main valve 160 .
  • the load spring 128 exerts a downward force on the sensor 190 and the valve stem 162 to displace the deformable valve member 164 away from the valve seat 166 and permit gas to flow through the passage 167 of the main valve 160 .
  • the passage 167 is open, gas flowing into the inlet chamber 132 passes through the passage 167 , to the stem cap 168 , and through the lateral openings 169 and the passage 142 to the outlet 140 .
  • the example fluid flow regulator valve 100 accomplishes the regulated flow of a fluid or gas at a desired pressure. If a greater than desired pressure of gas flows through the main valve 160 , the downstream pressure of the gas (e.g., at the outlet 140 ) will increase and produce an increase in the gas pressure exerted upon the sensor 190 .
  • the increased gas pressure causes the sensor 190 and the attached valve stem 162 to move upwardly so that the deformable valve member 164 moves into engagement with the valve seat 166 and closes the main valve 160 . More particularly, the sensor 190 and the attached valve stem 162 are urged upwardly by the increased pressure and cause the deformable valve member 164 to engage the first diameter surface 166 A of the valve seat 166 (see FIG. 2 ). The engagement of the deformable valve member 164 with the first diameter surface 166 A closes the passage 167 .
  • the deformable valve member 164 moves upwardly against the first diameter surface 166 A, the deformable member 164 deforms to receive therein the first diameter surface 166 A until the flat angled surface 164 B engages simultaneously the larger diameter second surface 166 B.
  • the flat angled surface 164 B and the larger diameter second surface 166 B are generally parallel to one another and, thus, their engagement results in a substantially uniform distribution of the forces exerted by the flat angled surface 164 B upon the larger diameter second surface 166 B. The substantially uniform distribution of the forces prevents the deformable valve member 164 from being damaged such that the valve member 164 could not close the passage 167 .
  • the example fluid flow regulator valve 100 could produce significant shifts of downstream pressure in the gas flow.
  • the simultaneous engagement of the flat angled surface 164 B with the first diameter surface 166 A and the larger diameter second surface 166 B prevents damage to the valve member 164 and the resulting undesirable flow of fluid or gas through the example fluid flow regulator valve 100 .
  • the deformable valve member 164 can deform as described above to prevent such damage.
